JAR-RING APPLIANCE FO'R BAILERS.

Application filed May 4, 1921.

To all whom t may concern.: f Be it known that JAMES E. lVHrrMILL and Isaac Buurman, Citizens of the United States of America, residing at Desdemona, in the county of Eastland and State of Texas, have invented new yand useful Improvements in Jarring Appliances for Bailers, of which the following is a specification.

The object of the invention is to provide simple and efficient means applicable to a bailer or' the type commonly employed in` connection with well drilling operations Jfor accomplishing the loosening' of the bailer when it becomes caught or jammed or otherwise locked against movement in the well, as a means ot avoiding the loss of time and inconveniences incident to loosening the same with the .means heretofore employed in this connection and to avoid the cutting of the sand line, and to this end the invention consists essentially in connecting with the cylinder or tube of the bailer which may be of the ordinary or any preferred form, construction or dimensions, a jarring appliance or attachment which can be operated by the spudding or pumping` beam o-r through any other convenient agency without injury either to the bailer or the other parts of the pump or well equipment; and further in certain details of construction and arrangement of which a preferred embodiment is shown in the accompanying drawing, where- 1n:-

Figure 1 is a view of a jarring appliance embodying the invention applied in the opera-tive position to a typical form of bailer.

Figures 2 and 3 are detail views respectively of the head and anvil elements attached to the kjarring stem and the bailer tube or cylinder.

The apparatus embodies a reciprocable jarring stem carrying upper and lower spaced heads 11 and 12 for alternate or selective contact with an intermediate anvil 13 secured to the tube or cylinder 14 of the bailer, the upper head preferably being formed with a suspending loop or eye 15 for attachment to a suitable operating cab-le or rope by which the jarring stem may be Serial No. 466,730.

reciprocated in a guide 16 consisting of a central bore formed in the anvil.

In the preferred embodiment of the invention the anvil element is constructed of a blank 'or length of bar of which the dimensions may be 3 x 3 inches cross sectionally and approximately 18 inches in length oli which the terminal portions may be drawn down under a trip hammer or the like to form arms or straps 17 for attachment by rivets 1S or the equivalents thereof to the wall ott the bailer tube or cylinder, the central unreduced portion of the blank being` bored for example to provide an opening of approximately one inch in diameter and then swaged out to form the guide 16 which ite-r a jarring stem of a diameter of 11/2l inches should be approximately 1% inches in diameter. The upper hammer head and loop, correspondingly, may be formed of a similar bar of a. thickness of 3 X 3 inches and a length of approximately 14 inches terminally heated and hammered to provide venlarged terminals adapted to be bent toward each other and welded together to provide a block having a bore of a diameter sufficient to receive the end oi the stem 10 which is preferably threaded therein as shown and is further secured by means of a key or pin 19, the intermediate portion of' the blank forming the loop or eye 15. The lower hammer head carried by the stem may be formed integral therewith by swag` ing or equivalent treatment, and in operation a series of impacts by one or the other of the hammer heads upon the anvil or of alternate impacts in opposite directions of said heads will serve to loosen the bailer under any.' of the circumstances tending to interfere 'with the free movement thereof, and without imposing upon the bailer a strain which will tend to distort the. same, and

-without involving the cutting of the sand line, or the injury of any of the other parts ot the drilling or hailing mechanism.

The invention having been described, what is claimed as new and useful is A jarring attachment for bailers consist ing in the combination with a bailer tube or cylinder, of. an anvil provided with diverg-` sa j 1,517,226

ing depending arms secured to said bailer and provided with a suspending' loop to tube or cylinder, the anvil being` axially which an operating cable may be attached; bored, a jarring stein slidably mount-ed in In testimony whereof they nflix their sig- 10 the bore of the anvil, and upper and lower natures. spaced heads carried by the stein abofe and below the anvil for alternate Contact with JAMES E.
